The invention discloses a dielectric sliding type phase shifter and a base station antenna. The dielectric sliding type phase shifter comprises a cavity, a feed network and a phase shifting unit. Thefeed network includes a functional circuit and phase shifting circuits. The surfaces of the phase shifting circuits are covered with dielectric plates, by rotating the dielectric plates, the length ofthe phase shifting circuits covered by the dielectric plates can be changed, and then the electrical length of a transmission line can be changed to realize phase adjustment.

Therefore, when the dielectric plates of the phase shifting units rotate around the axis passing through the center of the circle, the dielectric plates are limited within a circle range without exceeding the range of the corresponding phase shifting circuits. That is to say, the processes that the phase-shifting circuits realize phase adjustment are relatively independent. Therefore, functional circuits and phase shifting circuits can be designed independently, the design space of the circuit is greatly improved, the design difficulty of the phase shifter is greatly reduced, and the problem of limited design space of circuits in a traditional dielectric sliding type phase-shifter is solved.
